P(3 or 4) = 1/3, so she can expect to roll a 3 or 4 13 times
Answer:
0.97725
Step-by-step explanation:
Given :
Population mean, μ = 4.2
Population standard deviation, σ = 1.8
Sample size, n = 36
Obtain the Zscore of x = 4.8
Zscore = (x - μ) ÷ (σ / √n)
Zscore = (4.8 - 4.2) ÷ (1.8 / √36)
Zscore = 0.6 ÷ 0.3
Z = 2
Hence,
P(Z ≤ 2)
Using the Z probability calculator :
P(Z ≤ 2) = 0.97725
Step-by-step explanation:
Let angle 4 = x
Now
60° + 45° + x = 180°
reason : Sum of interior angle of triangle is 180° ...
105° + x = 180°
x = 180° - 105°
x = 75°
Hence , the value of angle 4 is 75°

hope this helps can i have brainly thing if so please
Step-by-step explanation:
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
Hope this helps.
